Plating in Corrosive Atmospheres
Plating in Corrosive Atmospheres
(OP)
I'm interested in hearing the experience of others with types of plating used in SO2 enviroments, (IE tin vs. silver) as well as other types of protection used.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Plating in Corrosive Atmospheres

RE: Plating in Corrosive Atmospheres
There are several different ways to approach this.
RE: Plating in Corrosive Atmospheres
Currently we use tin as much as possible, but recently the field maint had 600V breakers rebuilt with silver plating, which I know is more susceptable to Sulphur. I'm looking at replacing the stationary part of the breaker disconnects with tin plating. The manufacturer is going to test the temperature rise of this combination.

Hope this helps.
RE: Plating in Corrosive Atmospheres
Note that both silver and tin have equally comparable properties on corrosion resistance.
